2 dni temu · Mapping a city might involve determining where are the roads and the restaurants and the stores. Or at higher resolution, it might involve determining where is every tree and every house. The same is true for mapping a genome. Some genome maps reflect the location of big chromosomal regions.
3 dni temu · Gene mapping refers to the process of determining the location of genes on chromosomes. Today, the most efficient approach for gene mapping involves sequencing a genome and then using computer programs to analyze the sequence to identify the location of genes.
1 dzień temu · At the outset of each run, a random tree was initialized, and subsequently, every 1000 generations, a single tree was sampled, totaling 10,000,000 generations. The evaluation of convergence and stationarity was conducted using Tracer version 1.4 ( Rambaut and Drummond, 2007 ), and to ensure the convergence of runs, the initial 25% of trees were ...
4 dni temu · Lastly, the authors demonstrate that L1-derived enhancers have an essential role during zygotic genome activation (ZGA) by mediating long-range DNA interactions and activating ZGA-related genes ...

5 dni temu · Simulating an alignment from a tree and model. Similar to other software, AliSim can simulate a multiple sequence alignment from a given tree with branch lengths and a model with: iqtree2 --alisim <OUTPUT_PREFIX> -m <MODEL> -t <TREEFILE>.
1 dzień temu · The genetic distance between populations is often measured by Fixation index (Fst), based on genetic polymorphism data, such as single-nucleotide polymorphisms (SNPs) or microsatellites. Fst is a special case of F-statistics, the concept developed in the 1920s by Sewall Wright.
